Sepulchral Wine

#280821
Notes

Sepulchral Wine (#280821) is a deep magenta with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (313°, 67%, 9%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sepulchral
adjective

Latin sepulcrālis, of the burial-place — adjectival form of sepulcrum. As a color modifier, sepulchral implies the deep funereal-and-formal darkness of Holy-Sepulchre-and-rock-cut royal-tomb interiors of medieval-and-Renaissance Christendom. Sits at the deep-and-funereal end of the grid, parallel to entombed and funereal in tone, both literary and architectural.

Wine
noun

Fermented grape juice — the universal red of viticulture from Tuscany to Mendoza. Wine as a color refers specifically to a young Cabernet Sauvignon or Syrah in a glass: a saturated, slightly red-shifted deep purple-red with the optical clarity of a fluid free of suspended solids. Cooler than burgundy, warmer than mulberry, with the agricultural weight of a fluid whose color comes principally from anthocyanin pigment in the grape skin.
